Abstract:

Creative computing is very popular in recent years and has great potential. The introduction of systematic creative mechanisms and principles can provide solutions to practical problems, such as potential forgery and tampering of trade data in traditional supply chains. Guided by being creative, this paper proposes a new trusted data management scheme based on blockchain. First, a smart contract suitable for supply chain is designed to code trade rules in order to prevent performance risks and improve the credibility of trade data processing. Then, a ZSS04 scheme and sampling techniques are used to complete transaction data integrity check. Furthermore, an optimized PBFT consensus mechanism is proposed to achieve efficient, low cost, and scalable transaction data management. Finally, the trusted data management in untrusted environment is implemented by using the native characteristics of blockchain. Results show that the scheme can provide new ideas and technical support for transaction data management in supply chain.
